SEMICONDUCTOR STORAGE DEVICE AND METHOD OF THROTTLING PERFORMANCE OF THE SAME

摘要

A semiconductor storage device and a method of throttling performance of the same are provided. The semiconductor storage device includes a non-volatile memory device configured to store data in a non-volatile state; and a controller configured to control the non-volatile memory device. The controller calculates a new performance level, compares the calculated performance level with a predetermined reference, and determines the calculated performance level as an updated performance level according to the comparison result.

1. A method of ensuring an expected life of a semiconductor storage device (SSD) including a non-volatile memory device and a controller to control the non-volatile memory device, the method comprising:
monitoring an write workload of the SSD based on write commands received from a host device; receiving a first write command from the host device after changing a performance level of the SSD according to the write workload; and executing the first write command based on the changed performance level; wherein the performance level is decreased if the write workload of the SSD gets higher.
